Holding: The Board’s decision that Ciaravino should be disqualified from receiving unemployment benefits was not contrary to law and was supported by substantial evidence. Ford’s evidence was sufficient to show that Ciaravino’s positive drug test for marijuana, a controlled substance, disqualified him from receiving benefits.

Facts: Robert Ciaravino worked as an employee for Ford Motor Company from October 1994 until October 7, 2005. After he tested positive for marijuana during a random urinalysis, he was discharged. Ciaravino’s specimen was taken by Beverley Tukis, a Ford full-time nurse, and the positive drug results were received by Sally Gruca, another Ford full-time nurse.

Decision: The circuit court affirmed the Board of Review’s decision, which found the claimant to be disqualified from receiving benefits for misconduct under Section 29(1)(m) of the MES Act.

Rationale: Though Ciaravino denied using marijuana and said he had been taking Vicodin for a knee injury, there was no evidence that Vicodin would produce a false positive for marijuana or that the test was erroneous. Ciaravino had also signed a Reinstatement Waiver on April 4, 2005 in which he agreed to submit to random drug and alcohol testing as a condition of employment at Ford. The discharge of an individual due to ingestion of marijuana, which is considered a “controlled substance” pursuant to MCL 333.7104, 7201 and 7212, disqualifies the individual from receiving benefits. Ford also provided sufficient evidence to establish an adequate chain of custody from which a positive specimen result could be inferred.
